Bathroom Renovation Costs in Reservoir 2026

Reservoir is Melbourne's largest northern suburb by population and one of the most active renovation markets in the city. A generous stock of postwar weatherboards, mid-century brick veneers, and interwar homes on solid family-size blocks means Reservoir homeowners are constantly upgrading tired bathrooms — both to enjoy day to day and to add value.

Bathroom renovations are the second most common project we see in Reservoir after kitchens. Here is what they cost in 2026, what drives the price, and how to find the right builder.

What Affects Bathroom Renovation Cost in Reservoir

Waterproofing compliance

Waterproofing is the single most important element of any bathroom renovation and the most common source of expensive future problems. All waterproofing in Victorian bathrooms must comply with AS 3740 and must be carried out by a registered waterproofer. Budget

,000 to $4,000 for compliant waterproofing done properly the first time — cutting corners here is the single biggest false economy in a bathroom renovation.

Tile selection

Tiles are the biggest visible cost driver. Basic ceramic tiles from $30 per square metre. Mid-range porcelain from $60 to

20 per square metre. Premium large-format porcelain, natural stone, or feature tiles from
50 to $400 per square metre. A typical Reservoir bathroom needs 25 to 40 square metres of tile including walls and floor. Labour to lay tiles runs $70 to
30 per square metre depending on tile size and format.

Vanity and joinery

An off-the-shelf vanity from $600 to

,000. Semi-custom from
,500 to $5,000. Full custom joinery with stone tops from $5,000 to
2,000. Custom joinery makes the biggest visual difference in a small bathroom and is often worth the spend.

Structural changes for new bathrooms

Adding a new bathroom or ensuite involves extending plumbing and waste, running new electrical, framing walls, and integrating with existing structure. The plumbing rough-in alone typically adds $5,000 to

0,000 over a like-for-like renovation. Reservoir's older weatherboard and brick veneer homes are generally straightforward to modify structurally, keeping costs reasonable relative to inner-city period homes.

Tapware, fixtures, and shower screens

Budget tapware packages from $800. Mid-range from

,000 to $4,000. Premium from $5,000 to
2,000. A frameless shower screen from
,200 to
,500. Freestanding baths from
,500 to $6,000.

Does a Bathroom Renovation Add Value in Reservoir

Yes — and adding a second bathroom in particular delivers strong ROI in Reservoir. Many of the suburb's original postwar and interwar family homes were built with a single bathroom, which is a significant handicap in today's family buyer market. Adding a second bathroom or ensuite typically returns more than its cost at sale and dramatically widens the pool of interested buyers.

Even a straightforward renovation of an existing bathroom removes the "we'll have to redo the bathroom" discount that buyers apply mentally at inspection. For owner-occupiers, any uplift in value is exempt from capital gains tax when you sell — a fully tax-free return.

Finding a Bathroom Renovation Builder in Reservoir

Any builder carrying out structural bathroom work in Victoria must hold a current Domestic Builder licence. Check any builder's licence at vba.vic.gov.au before signing. Confirm public liability insurance of at least $5 million, ensure the waterproofer is registered, and always get a detailed written quote covering scope, inclusions, exclusions, timeline, and payment schedule.
